Sigma and Pi bonds

Why are sigma bonds stronger than pi bonds?

Sigma bonds are stronger than pi bonds because the electron clouds between atoms that have a sigma bond overlap more than those electron clouds would overlap in a pi bond. The more overlap between electron clouds in sigma bonds allows for a stronger electronegative attraction between shared electrons and opposing nuclei.

Because they are directly overlapping with the orbitals. Pi bonds are merely parallel with the orbitals

As stated above, the sigma bonds have more of an overlap in the electron cloud between the atoms, thus making the bond stronger.
